Abstract
The present invention is directed to a drilling fluid reclaimer. The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is “reclaimed” for use with a drilling system.
Claims19
A method comprising:
- using drill fluid in an excavation operation at a location;
- removing a used drill fluid from the location through a conduit to an airlock;
- regulating the flow of used drill fluid at an output of the airlock;
- desilting the used drill fluid;
- placing the used drill fluid on a first screen after the steps of regulating the flow and desilting the used drill fluid;
- maintaining a level side-to-side orientation of the first screen;
- vibrating the first screen to separate the used drill fluid into a particulate portion and a slurry portion;
- and
- reusing the slurry portion in excavation operations.
A method comprising:
- receiving a material in a chamber having an inlet port and a first exit port;
- applying a vacuum pressure to the chamber;
- regulating flow of the material out of the first exit port of the chamber;
- desilting the material after it has flowed from the first exit port;
- and
- thereafter, placing the material on a vibrating screen exposed to ambient conditions.
